key 15, the latch 16 of said lock being bev- Toall'whomitmaycmwem:

Be it known that I, WILLIAM C. Talent, a citizen of the United States, residin at Baltimore, in the county of Baltimore 'ity and State of Maryland, have invented new and useful Improvements in Automobile Locks, of which the following is a specification.

This invention relates to improvemen in automobile locks and has for its object to provide a chea simple and-efii'cient device to lock the mac 'ne so that it cannot be startt ed and also to lock the machine so it cannot be towed awa The invention consists of the novel construction and arrangement of the parts hereinafter more fully set forth in the specification and pointed out in detail in the appended claims. p

In the accompanying drawings Figure 1 is a side elevation of my invention, the clutch casing being shown in section. I

Figure 2 is a detail view of the lever and shaft for operating the slidable clutch facet Referring to the accompanying drawings forming part of this specification and in which like reference numerals designate like parts throughout the several views thereof, 21 designates the clutch casing through which the driver shaft ro'ects. The said driver shaft is compose 0 .two sections 1 and 2 the section 1 being connected with the engine in the front of the machine and the section 2 bein connected with the rear of the machine. The front section 1 is provided with a clutchface 3 which is providedwith internal gears 4 and is fast on the end of the section 1 of said drive shaft. The other face.

5 of the clutch is slidably mounted on the end of the section 2 of the drive shaft and is provided with external teeth 6 adapted to mesh with the internal teeth on the face 3 of the clutch. The said clutch 5 is provided with an annular groove 7 into which is fitted the rollers 8 on the arms 9, the latter bein mounted on the shaft 10 which is operate by the lever 11 for moving the slidable face 5 into and out of gear with the .clutch face 3. The case 21 is rovided with a bolt 12 ads. ted to be forced 7 of the clutch face 5, the said bolt 12 bein held normally-out of engagement with said slot 7 by the spring 13. The casing 21 is also provided with a lock 14 operated by the into the groove 7 and the into the annular groove 18, 1980. Application for elled on one end and adapted to beset 1n the bevelled cut-out 17 in the side of the bolt 12.

groove 7 and the face 5 can be moved back and forth on the section 2 of the drive shaft by operating the lever 11, When it is desired to lock the machine the clutch face 5 is drawn back out of engagement with the clutch face 3 andthe bolt 12, is then pushed down against the action of the latch 16 springs into the recess 17 in which sition the bolt will be held and the clutcii face 5 locked.

sprln 13 against movement along the section 2 ofthe 1 drive-shaft in which osition the machine cannot be operated untll the latch 16 is withdrawn from the recess 17 by means of key 15. The rear end of the case 21 is provided with a sliding bolt 18 adapted to engage one of the cut-outs 19 on the rear of the clutch face 5; thesaid bolt 18 being held in the normal position by the coil sprlng 20. 'When the clutch face 5 is drawn out of engage ment with the clutch face 3 the pin 18 will enter one of the cut-outs 19 and prevent the rear section 2 of thedrive shaft from being turned which locks the rear wheels of the machine and prevents it from being towed away. As the clutch face 5 is moved for-- ward it will not engage the face 3 until the rear end has completely passed the end of the bolt 18. Should the space on the rear of the clutch face 5 between the cut-outs 19 strike the end of the bolt 18 the latter will be pushed back against the action of the coil spring 20 and any attempt to move the car will cause sufficient revolution of the section 2 of the drive shaft to allow the said bolt to spring into one ofthe cut-outs 19.

It will. thus be seen that by the use of my invention the machine can be locked or so operated so that itfcannot be started and that the rear of the machine is so looked that it cannot be towed awa Having thus described my invention what I claim isz V 1. An automobile lock comprising a clutch casing, a driveshaft comprising two sections each projecting into said clutch casing, a clutch face fixed to the end of one of the sections of said drive shaft and havin in-' shaft and having an annular recess therein and external gear teeth, a shaft mounted in said casing at right angles to the drive shaft and having two arms projecting therefrom, a roller on the end of each of said arms and projecting ixito said recess in the slidable clutch face, a lever to o erate said last namedshaft to throw the'sli able clutch face into or out of engagement with the other clutch face, abolt adapted to project into the recess in the slidable clutch face, a spring to hold the said bolt normally out of engagement with the 'slidable'clutch'face, and a 100k to hold the bolt in the slidableicl'utch face. Y

2.
